What I'm looking for

I seek a role where I can improve service reliability and SLOs, reduce incidents, mentor teams, and optimize infrastructure costs while working with Kubernetes, IaC, and robust monitoring in a collaborative environment.

I am a DevOps and Infrastructure Engineer with deep expertise in Kubernetes, Linux, and infrastructure-as-code, focused on improving reliability and optimizing costs. I have a proven track record delivering measurable results—reducing incident rates ~4x, supporting 2.5x infrastructure growth, and achieving >20% budget savings while maintaining SLOs.

I excel in building and maintaining bare-metal and cloud-native platforms, implementing monitoring, SIEM and database observability, and resolving legacy technical debt. I collaborate across small and large teams, lead incident response and post-mortems, and drive organizational and technical improvements to increase service stability and operational efficiency.
